To all 107mm if may concern.' y Q Be 1t known that CHARLES NATHANIELTAYLOR, a citizen of the United Statesof America, yresiding atHemingford, in they countyfof Box `Butte and State of Nebraska,

has invented new and useful Improvements,

in Ditching, Grading, and Back-Filling Machines, of which the followingis a specification.

The object of the invention is to provide a machine of the typeordinarily employed for ditching and grading wherein the' scoops aremounted for movement in paths trans-y verse to that of the machine andrespectively 1n advance of and followmgthe machine-or the. supportingtruck thereof for opening the path fory the machine truck to the endthat" the mechanism may operate in a substantially uniform plane in itsprogressive movement and furthermore to economize in the ex penditure ofpower and time in the removal of the soil by arranging the 'scoops andthe means for operating the same to successively traverse the same pathin opposite directions and in alternate relation; and to provideefficient joint means for successivelyv dumping the scoops with relativeuniformity and under the control of an operator positioned to controlthe truck mechanism and the motor by which the same is actuated; andwith these objects in view the invention consists in a construction andcombination Lof parts of which a preferred embodiment is shown in theaccompanying wherein Figure 1 is a plan view, and Figure 2 is a sideview of a mechanism embodying the invention. f

Figure 4 is a detail view of a portion of the traction cable.

Figure 5 is a detail view illustrating'a supplemental traction cable. fl

The framework of the machine embodies essentially a truck 10 consistingin the construc-y tion illustrated of the longitudinal beams 11supported by the axially pivotal wheels 12 of conventional form andmounting and a bracing wheel 13 carried by an extension'fr'ame 14 andmounted upon a fixed spindle to follow a path in substantial parallelismwith the main wheels 12, and a superstructure carried by the truck andhaving an' uprightor mast 15 suitably braced, with a boom 16 pivotallymounted for adjustment in angular position on the ktruck and held in thedetions laterally and rearwardly from the truck are front and rearspacing arms 2O pro-l vided terminally with pulleys 21 for the hoistingcable 22, terminally reeled upon the hoistingk drum 23 and extendingfrom the extremities of the spacing arms forwardly on convergent linesto and around a direction pulley 24near the outer endof the boom. Thescoops 25' of whichfone o-r more may be employed for each run of thehoisting cable, a run being referred toas the portion of the cablebetween'each guy-pulley 21 and the direction pulleyy 24, are' connectedwith the hoisting cable by front and rear chains 26, and'27 orsim'ilarflexible means suitable for the purpose indicated, the formerbeingv connected in eachinstance as at 28 to permit of the tilting anddirection of the scoop by means of the manually' operable handles 29scoop. f y

Pivotally mounted for swinging movement in' a vertical plane in asuitable fork 30 aty the free end ofthel boom is a dumping bar 31'fromthe lowerjend Aof which extends an operating cable 32, preferably aroundone or more intermediate guy-pulleys 33 on the boom to anoperating drum34 which in the construction illustrated and preferably is located in'co-axial relation with the hoisting drum 23 and is within convenientcontrol of an'engineer or" other operative ystationed' on the seat 35`and therefore in a position to clearly observe the operations of all ofthe scoops. l f

Extending-around the guyspulley 36 carried yby the upper end of thedumping bar is what may be termed a continuous dump' ing cable 37 inthat its'terminals are con. nected with thehoisting cable at thepoints'l of connection yof the rear chains 27 of thev scoops with saidhoistingcable, to the end that when the dumping cable is tensioned bythe tilting of the dumpingfbar through the t'ensioniin'ry n of theyoperating cable 32, it oper# ates'to tilt and dump ythe scoop which isloaded and which is advancingin the direction of they arrow a in Figure1, because the portion of the hoisting cable in rear of ythey loadedbucket is slackowing to the fact that making connection between thescoop traversing the opposite path or on the'other .run of the hoistingcable as indicated by the arrow b, is retracing its move= ment or isproceeding rearwardly, after being emptied or dumped, preparatory toreceiving a fresh load. l

Assuming that the direction of progress of the ditching or gradingoperation is as indicated by the arrow c on Figure l, it will be obviousthaty the scoop which is actuated by that run of the hoisting'cablewhich is in advance of the truck will serve to remove soil in the pathof the truck to prepare a way therefor while the scoop operating inconnection with the other run of thehoisting cable will complete theoperation tothe re-l quired depth, and the progress of the trucktherefore may be at a comparatively uniform level, and may be effectedfor example by the stretching of a cable 38 parallel with the pathdesired for its progress and stepped or spaced rings 39 thereof,arranged at any suitable intervals adapted for the advance of the truckfrom time to time, and the hoisting drum or the equivalent thereofthrough a supplemental traction cable 40, so as to move the machine therequired distance in a step by step manner as the work proceeds, saidarrangement of the advancing cables being indicated in ligure 3.

Having described the invention, what is claimed as new and useful is 1.A machine of the type indicated having-a truck carrying a laterallyextending boom, and a scoop carryinghoisting cable provided with runsextending transversely respectively in front and in rear ofthe truck andbetween the longitudinal plane of the latter and the outer end of theboom and on transversely convergent lines. v

2. A machine of the type indicated having a longitudinally movabletruck, a boom carried by and extending laterally in one direction `fromthe truck, and front and rear arms extending laterally in the oppositedirection from they truck, said boom and arms being provided withterminal guiding means, and

a scoop carrying hoisting cable traversing said guiding means and havingruns extending from the extremities of said arms in convergent relationstoward thev guiding Y means of the boom.
